From its inception in 1906 when John C. Theus relocated to Monroe to practice law, the firm now known as Theus, Grisham, Davis & Leigh has occupied various buildings in the city of Monroe. We started out in1906 in the Bernhardt Building and stayed there until1957. Then we moved to South Grand Street and stayed there until 1975. At that time, our company had expanded and we required more space. We relocated to Bancroft Circle and stayed there until 1985. With the addition of both partners and staff, Theus, Grisham Davis, and Leigh needed a larger office, and we decided to build a new office on Lamy Lane. We had a brief stay in temporary quarters in the Louisiana Bank Building while construction was completed. We sold the Lamy Lane office in 2011 and moved into our present location at 3139 Mercedes Drive on June 1, 2011.
